Greetings Elf2232,
To clarify, do you need to restore fonts that were originally included with your Mac? If so, the following steps may be able to assist you:
- "In the Font Book app
on your Mac, choose Font Book > Settings. - Click Advanced, then click Reset Fonts.
- Click Proceed to confirm, and enter your password if asked (or use Touch ID).
Any fonts you’ve installed are placed in /Library/Fonts (Removed) or in ~/Library/Fonts (Removed). To install those fonts again, just reinstall them."
